Thereafter, a step of tilting the operated beam 22a (to be described later) to switch the posture of the operated beam 22a (S002), and a step of fixing the balcony unit side trunk piece 15 to one longitudinal end of the operated beam 22a (S003). ), The step of switching the attitude of the operated beam 22a again so that the fixed balcony unit side trunk piece 15 is located at a predetermined position (S004), and the balcony unit side trunk piece 15 located at the predetermined position. The assembly operation of the balcony unit 10 is completed through the step (S005) of connecting the above to the above-described one set of the body-side trunk difference pieces 21a and 21b. Hereinafter, each process is explained in full detail.

<Step S001 for Preparing Balcony Unit 10 and Housing 20>
This step S001 is a step of transporting the balcony unit 10 with the balcony unit side trunk piece 15 from the assembly factory to the construction site when the balcony unit 10 is assembled. In the balcony unit 10 of the present embodiment, a set bolt 16 is attached to a predetermined portion of the balcony unit-side trunk piece 15 of the balcony unit 10 (see, for example, FIG. 7B). When the balcony unit 10 is assembled to the housing 20 of the building body 2, the set bolt 16 is engaged with an engagement hole 23a formed in the housing 20 (the engagement hole 23a will be described later). The lower end portion of the balcony unit side body differential piece 15 is attached to the balcony unit side body differential piece 15 in a state where it protrudes somewhat from the lower end of the balcony unit side body differential piece 15. In addition, the protrusion amount of the set bolt 16 in this embodiment is about 40 mm.

  On the other hand, in this step, the housing 20 of the building body 2 is prepared in the same manner as the preparation of the balcony unit 10. Here, the casing 20 needs to be in a state in which the balcony unit 10 can be assembled. More specifically, when the preparation of the balcony unit 10 is completed, the housing 20 of the building body 2 is provided with a pair of housing-side trunk difference pieces 21 a and 21 b and a plurality of floor beams 22. A gap is formed between the pair of housing-side trunk differential pieces 21a and 21b so that the balcony unit-side trunk differential piece 15 enters. In other words, when the balcony unit 10 is assembled, the pair of housing-side trunk difference pieces 21a and 21b are in a state of being linearly arranged with the gap therebetween.

  Furthermore, before the balcony unit 10 is assembled to the housing 20 of the building body 2, one of the plurality of floor beams 22 is in a state where one end in the longitudinal direction faces the gap. That is, as shown in FIG. 8, in the frame 20 before the balcony unit 10 is assembled, one floor beam 22 is connected to the frame side trunk piece 21a in the direction in which the pair of frame side trunk pieces 21a and 21b are arranged. , 21b, and one longitudinal end (front end) of the one floor beam 22 is located beside the gap in the front-rear direction of the building body 2 (the rear end of each pair of housing side trunk differences 21a, 21b). Position). Hereinafter, the floor beam 22 provided so that one end portion in the longitudinal direction faces the gap is referred to as an operated beam 22a. Naturally, the operated beam 22a is an example of a beam member provided on the casing 20 so as to intersect with a direction in which the pair of casing-side trunk difference pieces 21a and 21b are arranged. FIG. 8 is a diagram showing the positional relationship between the operated beam 22a and the gap.

  Also, immediately below the gap, a receiving member 23 is provided that receives the balcony unit side trunk piece 15 when the balcony unit 10 is assembled to the housing 20 of the building body 2. An engagement hole 23a is formed. Here, the receiving member 23 is, for example, a horizontal member, an intermediate column, a pipe column, or an outer wall member that is positioned below the trunk difference 21 in the housing 20.

  Under the above circumstances, the prepared balcony unit 10 is lifted to be assembled at a predetermined position of the housing 20 of the building body 2. Then, the suspended balcony unit 10 maintains the posture in which the front end is located above the rear end (specifically, the posture located above the amount corresponding to the protruding amount of the set bolt 16) It is moved toward the predetermined position. The method for hanging the balcony unit 10 and the jig 30 used when hanging the balcony unit 10 will be described in detail later.

<Step S002 for switching the posture of the operated beam 22a>
This step S002 is a step of switching the posture of the operated beam 22a by tilting the operated beam 22a when one end in the longitudinal direction of the operated beam 22a faces the gap. More specifically, in the stage before this step S002 is executed, the operated beam 22a has one end in the longitudinal direction facing the gap, and the longitudinal direction is in the horizontal direction. is there. Hereinafter, the posture of the operated beam 22a in this state is referred to as a first posture. Thereafter, by the execution of this step S002, the operated beam 22a is tilted so that one end portion in the longitudinal direction is positioned higher than the other end portion in the longitudinal direction. Hereinafter, the posture of the operated beam 22a in this state is referred to as a second posture. In the present embodiment, the second posture is such that one end (front end) in the longitudinal direction of the operated beam 22a is positioned above the other end (rear end) in the longitudinal direction by an amount corresponding to the protruding amount of the set bolt 16. It is the posture of the state.

  Hereinafter, a specific procedure for switching the posture of the operated beam 22a as described above will be described with reference to FIG. FIG. 9 is a diagram showing a mechanism for switching the posture of the operated beam 22a.

  In performing this step S002, first, as shown in FIG. 9, a slight space is provided at a position below one end portion in the longitudinal direction of the operated beam 22a and is long in a direction intersecting with the longitudinal direction of the operated beam 22a. A single pipe 40 is laid. At this time, the single tube 40 is supported by a support member 40 a provided in the housing 20 of the building body 2. Next, a jack 41 as a beam receiving member is installed between the single tube 40 and one end in the longitudinal direction of the operated beam 22a. The jack 41 is fixedly supported by a fastener 41a provided on the single tube 40 side. Thereby, the longitudinal direction one end part of the to-be-operated beam 22a comes to be supported by the jack 41. FIG. Thereafter, the operation of the jack 41 raises one longitudinal end of the operated beam 22a, and the operated beam 22a is tilted. As a result, as shown in FIG. 7A, the position of the operated beam 22a is switched from the first position to the second position, and thereafter, one end in the longitudinal direction of the operated beam 22a is continuously supported by the jack 41. The posture is maintained in the second posture.

  This step 002 is executed by the procedure as described above. Note that the execution time of this step 002 may be before the balcony unit 10 is lifted or after it is lifted. Further, the installation work of the single pipe 40 and the jack 41 and the operation of the jack 41 can be performed inside the building body 2.

<Step S003 of fixing the balcony unit side trunk piece 15 to the operated beam 22a>
This step S003 is performed after the step S003 for switching the posture of the operated beam 22a from the first posture to the second posture, and is lifted to one end in the longitudinal direction of the operated beam 22a in a state where the posture is in the second posture. This is a step of fixing the balcony unit side trunk piece 15 in a state of being damaged.

  In the present embodiment, when executing this step S003, the balcony unit 10 is lifted so that the front end of the balcony unit 10 is higher than the rear end by an amount corresponding to the protruding amount of the set bolt 16. It is adjusted to be positioned. On the other hand, the posture of the operated beam 22a is adjusted so that one end in the longitudinal direction of the operated beam 22a is positioned higher than the other end in the longitudinal direction by an amount corresponding to the protruding amount of the set bolt 16. . In other words, in this embodiment, as shown in FIG. 7B, the operated beam 22a is tilted to the same extent as the inclination of the balcony unit 10. As a result, an operation for fixing the balcony unit side trunk piece 15 to one end portion in the longitudinal direction of the operated beam 22a (for example, a joining operation using a bolt or the like) is smoothly performed. And if this process S003 is completed, the balcony unit 10 will be in the state connected with the to-be-operated beam 22a via the balcony unit side trunk piece 15 (for example, refer FIG.7 (C)).

<Step S004 for switching the attitude of the operated beam 22a again>
This step S004 is a step that is executed after the balcony unit side trunk piece 15 is fixed to one longitudinal end portion of the operated beam 22a, and returns the posture of the operated beam 22a from the second posture to the first posture. By this step S004, the balcony unit side trunk difference piece 15 fixed to one end in the longitudinal direction of the operated beam 22a is located in the gap between the pair of frame side trunk difference pieces 21a and 21b. Are sandwiched between the body-side trunk differential pieces 21a and 21b. That is, this step S004 is performed on the balcony unit side so that the balcony unit side trunk piece 15 is disposed in the gap between the pair of housing side trunk pieces 21a and 21b through the operation of the operated beam 22a. This is a step of moving the balcony unit 10 provided with the trunk difference piece 15 and the balcony unit side trunk difference piece 15.

  Hereinafter, a specific procedure for returning the posture of the operated beam 22a from the second posture to the first posture will be described.

  After the balcony unit side trunk piece 15 is fixed to one end portion in the longitudinal direction of the beam to be operated 22a, the one end portion in the longitudinal direction is dropped by its own weight by the operation of the jack 41. As a result, the longitudinal direction of the operated beam 22a is aligned with the horizontal direction (that is, the attitude of the operated beam 22a returns to the first attitude). In this process, the balcony unit side trunk difference piece 15 fixed to one end portion in the longitudinal direction of the operated beam 22a comes to be positioned in a gap between the pair of body side trunk difference pieces 21a and 21b. Further, when the balcony unit side trunk piece 15 is positioned in the gap, the set bolt 16 attached to the balcony unit side trunk piece 15 is engaged with the engagement hole 23a of the receiving member 23 provided immediately below the gap. (See FIG. 7D).

  Thus, in this embodiment, the balcony unit side trunk difference piece 15 comes to be arrange | positioned in a predetermined position by switching the attitude | position of the to-be-operated beam 22a. In other words, in the step S003 for fixing the balcony unit side trunk piece 15 to one end in the longitudinal direction of the operated beam 22a, the balcony unit side trunk piece 15 when the attitude of the operated beam 22a is returned to the first position. Is fixed at one end in the longitudinal direction of the operated beam 22a so that the set bolt 16 can be engaged with the engagement hole 23a. I will let you.

  And the balcony unit side trunk difference piece 15 located in the gap is positioned at the same height as the pair of frame side trunk difference pieces 21a and 21b in the vertical direction while filling the gap and receiving the support by the receiving member 23. It becomes like this. In addition, after completion of this process S004, the single pipe 40 and the jack 41 mentioned above will be removed from the housing 20 of the building main body 2. FIG.

<Step S005 for Connecting Balcony Unit Side Body Difference Piece 15 to Housing Side Body Difference Pieces 21a and 21b>
In this step S005, the balcony unit side torso piece 15 that is positioned at the same height as the pair of case side torso pieces 21a and 21b in the previous step S004 is replaced with the set of body side torso pieces. This is a step of connecting to each of the pieces 21a, 21b. By this process S005, the balcony unit side trunk difference piece 15 comes to function as a part of the trunk difference 21 together with the pair of casing side trunk difference pieces 21a and 21b in the casing 20 of the building body 2. And the assembly | attachment operation | work of the balcony unit 10 is completed by completion of this process S005.

<< Effectiveness of Assembling Method of Balcony Unit 10 of this Embodiment >>
As described above, in the method for assembling the balcony unit 10 of the present embodiment, one floor beam 22 (i.e., one end in the longitudinal direction faces the gap between the pair of frame-side trunk difference pieces 21a and 21b) (i.e. The beam 22a) is tilted to switch the posture of the floor beam 22 from the first posture to the second posture. When the posture is the second posture, the balcony unit side trunk piece 15 is placed at one end in the longitudinal direction. To fix. Thereafter, by returning the posture of the floor beam 22 to which the balcony unit side torso piece 15 is fixed to the first position, the balcony unit side torso piece 15 is located in the gap and the pair of housing side torso pieces are set. It comes to be sandwiched between the pieces 21a and 21b.

  With the above assembling method, a series of operations for assembling the balcony unit 10 to the housing 20 of the building body 2 can be performed from the inside of the building body 2.

  More specifically, in order to assemble the balcony unit 10 to the housing 20 of the building body 2, it is necessary to fit the balcony unit-side torso piece 15 into a gap between the pair of body-side torso pieces 21a and 21b. is there. Here, when the above-mentioned floor beam 22 (that is, the floor beam 22 corresponding to the operated beam 22a) is placed in the normal position and the balcony unit side trunk piece 15 is to be fitted into the gap, The balcony unit side trunk piece 15 easily collides with the floor beam 22.

  On the other hand, in this embodiment, when the balcony unit side trunk piece 15 is fitted into the gap between the pair of housing side trunk pieces 21a and 21b, first, the manipulated beam 22a is tilted to perform the manipulation. The balcony unit side trunk piece 15 is fixed to one end portion of the beam 22a in the longitudinal direction. Thereby, it becomes possible to avoid the danger of the collision mentioned above. And about the to-be-operated beam 22a of the state to which the balcony unit side trunk piece 15 was fixed, the attitude | position is returned to the original attitude | position (namely, it returns to a normal position), The balcony unit side trunk piece 15 is made into the above-mentioned It becomes relatively easy to fit in the gap.

  Furthermore, in the present embodiment, when switching the posture of the operated beam 22a from the first posture to the second posture, one end in the longitudinal direction of the operated beam 22a is lifted, and the above posture is restored from the second posture. In returning to the first posture, the lifted one end in the longitudinal direction is dropped by its own weight. According to such a simple procedure, in the present embodiment, it is possible to more easily perform the assembling work of the balcony unit 10.

<< About the jig 30 for hanging the balcony unit 10 >>

The shackle 50 is an example of a hanging tool used when hanging the balcony unit 10. And the formation position of said attachment hole 38a turns into the above-mentioned hanging position.

  The suspension position adjustment mechanism 33 having the above-described configuration includes an attachment hole 38 a formed in the shackle attachment portion 38 and can move along the longitudinal direction of the support plate 32. Specifically, when the slide member 36 slides along the longitudinal direction of the support plate 32, the slide member 36, the fixed portion 37, and the shackle mounting portion 38 are integrally formed along the longitudinal direction of the support plate 32. Moving. Thereby, the relative position of the suspension position adjustment mechanism 33 with respect to the support plate 32 can be changed. That is, the formation position of the attachment hole 38 a, that is, the hanging position can be changed in the longitudinal direction of the support plate 32.

  The drive mechanism 34 is for moving the suspension position adjusting mechanism 33 along the longitudinal direction of the support plate 32. As shown in FIGS. 10 and 11, a ball screw 34a and a nut 34b as a rotating screw body are provided. Have

  The ball screw 34a is disposed above the support plate 32 and has a length extending from one end in the longitudinal direction (end on the free end side) of the support plate 32 to the other end in the longitudinal direction (end on the fixed end side). The ball screw 34 a is rotatably supported by the support plate 32 in a state where the central axis direction is along the longitudinal direction of the support plate 32. An operated portion 34c that is operated by an operator is formed at one end in the central axis direction of the ball screw 34a (an end on the fixed end side in the longitudinal direction of the support plate 32). When the operated portion 34c is operated using, for example, an impact wrench, the ball screw 34a rotates about its central axis. The ball screw 34a can be rotated in either the forward direction or the reverse direction.

  The nut 34b has a through hole through which the ball screw 34a is inserted. The nut 34b is fixed to the above-described slide member 36 in a state in which the ball screw 34a is inserted into the through hole and screwed into the ball screw 34a. Specifically, as shown in FIG. 11, the nut 34 b is located above the support plate 32 and is fixed to the side wall 36 a at a position sandwiched between a pair of side walls 36 a included in the slide member 36. Yes.

  The nut 34b moves along the central axis of the ball screw 34a when the ball screw 34a inserted into the nut 34b rotates (more precisely, when the ball 34a rotates relative to the nut 34b). As described above, the ball screw 34a can rotate in either the forward direction or the reverse direction, and when the ball screw 34a rotates in the forward direction, the nut 34b moves from one end to the other end in the central axis direction. When the ball screw 34a rotates in the reverse direction, it moves in the direction from the other end to the one end. In order to prevent the nut 34b from falling off the ball screw 34a, it is desirable that a locking member (stopper) 34d is provided at the end of the ball screw 34a.

  In the drive mechanism 34 configured as described above, the operated portion 34c of the ball screw 34a is operated, whereby the ball screw 34a rotates relative to the nut 34b, whereby the nut 34b is moved to the ball screw. It moves along the direction of the central axis of 34a. Accordingly, the slide member 36 to which the nut 34 b is fixed moves along the longitudinal direction of the support plate 32. As a result, the entire suspension position adjustment mechanism 33 including the slide member 36 moves along the longitudinal direction (in other words, the relative position of the suspension position adjustment mechanism 33 with respect to the support plate 32 changes). As described above, the suspension position is finally adjusted along the longitudinal direction of the support plate 32 by the movement of the suspension position adjustment mechanism 33.

<< About the hanging method of the balcony unit 10 using the jig 30 >>
Next, a hanging method for hanging the balcony unit 10 of the present embodiment using the jig 30 having the above-described configuration will be described. The suspension method is practiced in the suspension work described below. Hereinafter, the suspension work will be described with reference to FIGS. 14 (A) and 14 (B). FIG. 14A and FIG. 14B are diagrams showing a procedure related to the hanging work of the balcony unit 10 using the jig 30.

  When the balcony unit 10 is suspended, first, the jig 30 described above is attached to the balcony unit 10 so as to be in the state shown in FIG. More specifically, the engaging portion 31 of the jig 30 is engaged with the balcony unit-side trunk piece 15 so that the longitudinal direction of the support plates 32 provided on the left and right sides is along the front-rear direction of the balcony unit 10. . More specifically, as described above, the engaging portion 31 of the present embodiment has a bowl shape, and is an end portion of the upper flange portion 15a of the H-shaped steel provided in the central portion of the balcony unit side trunk piece 15. Is engaged with the H-shaped steel. When this engagement operation is completed, the jig 30 is attached to the balcony unit 10 so that the longitudinal direction of the support plate 32 is along the front-rear direction of the balcony unit 10. At this time, substantially the entire jig 30 including the support plate 32 is disposed inside the balcony unit 10 (in the space S in the balcony unit 10) (see FIG. 12).

  In addition, the attachment operation | work of the jig | tool 30 to the balcony unit 10 is normally performed in the state which left the said balcony unit 10 on the mount frame 51. FIG. In addition, it is good also as attaching the above-mentioned set bolt 16 to the balcony unit side trunk piece 15 in the state which protruded from the lower end of the balcony unit side trunk piece 15 somewhat in the case of the said attachment operation | work.

In other words, in this embodiment, there are two hanging positions in the width direction of the balcony unit 10 when hanging the balcony unit 10 to which the jig 30 is attached.

  Thereafter, using the drive mechanism 34 corresponding to each suspension position adjustment mechanism 33, the position of each suspension position adjustment mechanism 33, that is, each suspension position is adjusted. More specifically, the ball screw 34a is rotated by an impact wrench, and the nut 34b is moved along the central axis direction of the ball screw 34a. As a result, the slide member 36 to which the nut 34 b is fixed, the fixed member 37, and the shackle mounting portion 38 are integrally moved along the longitudinal direction of the support plate 32. As a result, the hanging position is adjusted in the longitudinal direction of the support plate 32, that is, in the front-rear direction of the balcony unit 10.

  By performing the adjustment operation of the hanging position as described above, it is possible to adjust the hanging posture when the balcony unit 10 is lifted. To explain in an easy-to-understand manner, the relative positional relationship between the suspension position and the gravity center position of the balcony unit 10 (more precisely, the gravity center position of the balcony unit 10 with the jig 30 attached) is changed by adjusting the suspension position. . As a result, it is possible to adjust the hanging posture when the balcony unit 10 is lifted. In particular, in the present embodiment, since the suspension position is adjusted in the front-rear direction of the balcony unit 10, the above-described suspension posture is adjusted by the inclination of the balcony unit 10 in a suspended state (more specifically, in the horizontal direction). The inclination of the balcony unit 10 with respect to the front / rear direction) is adjusted.

  The adjustment of the hanging position is roughly performed at the stage where the balcony unit 10 is still on the gantry 51. The adjustment at this stage is performed so that the hanging posture of the balcony unit 10 approaches a predetermined posture as much as possible at the so-called ground cutting stage (the stage where the balcony unit 10 is lifted and separated from the gantry 51). Thereafter, the hook 52 is hung on the shackle 50 and the balcony unit 10 is lifted through the jig 30. After the ground cutting, the hanging position is finely adjusted in the same procedure as described above. By this fine adjustment, the hanging posture of the balcony unit 10 is adjusted so that the front end thereof is positioned above the rear end by an amount corresponding to the protruding amount of the set bolt 16 (see FIG. 7B).

  If it demonstrates concretely, in the conventional jig | tool, in order to adjust the said hanging position, it was supposed to switch the attachment position of the jig | tool with respect to a balcony unit, for example. As a result, it takes time to adjust the hanging position, and there is a risk of damaging each part of the balcony unit. Furthermore, when the balcony unit is lifted using a conventional jig, the hanging position is adjusted by switching the mounting position of the jig as described above, so that the hanging position can be adjusted while the balcony unit is lifted. It was difficult.

  On the other hand, in the case of the jig 30 of the present embodiment, the suspension position is adjusted by moving the suspension position adjustment mechanism 33 provided on the jig 30 side along the longitudinal direction of the support plate 32. Is possible. Thereby, compared with the past, it becomes possible to easily adjust the hanging position. Also, with this configuration, it is possible to adjust the hanging position while the balcony unit 10 is being lifted. Furthermore, since the jig 30 according to the present embodiment is attached by engaging the engagement unit 31 with the balcony unit-side trunk piece 15 provided in the balcony unit 10, damage to each part of the balcony unit 10 is avoided. It is also possible.

  Further, the jig 30 of the present embodiment is provided with one set of each of the engaging portion 31, the support plate 32, the suspension position adjusting mechanism 33, and the drive mechanism 34 at both ends of the connecting member 35. The position adjustment mechanism 33 and the other suspension position adjustment mechanism 33 are each provided with an attachment hole 38a for attaching the shackle 50. However, the present invention is not limited to such a configuration. For example, the configuration includes one engagement portion 31, one support plate 32, one suspension position adjustment mechanism 33, and one drive mechanism 34 (that is, a one-point suspension configuration). May be. However, with the configuration of the present embodiment, the balcony unit 10 can be suspended at two points, and the suspension posture of the balcony unit 10 can be stabilized.

  Moreover, in the jig | tool 30 of this embodiment, it was decided that each engaging part 31 was hook shape. And when the balcony unit side trunk | drum 15 has H type steel like this embodiment, each engaging part 31 is said H by hooking on the edge part of the flange parts 15a and 15b of the said H type steel. Engage with the steel. However, the engaging portion 31 is not limited to the above-described shape, and may have any shape as long as it can engage with the balcony unit side trunk piece 15. However, if it is the structure of this embodiment, it will become possible to engage the engagement part 31 with the balcony unit side trunk | drum difference piece 15, and to stabilize the engagement state.

  Furthermore, the jig 30 of the present embodiment has a drive mechanism 34 for moving the suspension position adjusting mechanism 33 along the longitudinal direction of the support plate 32. The drive mechanism 34 has a ball screw 34a and a nut 34b. The ball screw 34a is operated along the longitudinal direction of the support plate 32 by operating an operated portion 34c formed at the end thereof. The nut 34b rotates along the central axis, and the nut 34b moves along the direction of the central axis by the rotation of the ball screw 34a. Thereby, the slide member 36 to which the nut 34b is fixed slides along the longitudinal direction of the support plate 32, and the entire suspension position adjusting mechanism 33 including the slide member 36 moves along the longitudinal direction. .

  However, the present invention is not limited to this configuration, and may be another drive mechanism 34 different from the above configuration as long as the suspension position adjustment mechanism 33 is moved along the longitudinal direction of the support plate 32. . Further, the drive mechanism 34 may not be a component of the jig 30. However, the suspension position adjustment mechanism 33 of the present embodiment makes it possible to adjust the suspension position more easily.

  More specifically, in the present embodiment, movement of the suspension position adjusting mechanism 33, that is, adjustment of the suspension position is performed by a relatively simple operation (specifically, by operating the operated portion 34c of the ball screw 34a). Yes. Furthermore, in a state where the jig 30 of the present embodiment is attached to the balcony unit 10, the operated portion 34 c faces the rear side of the balcony unit 10. Accordingly, if fine adjustment of the hanging position (that is, fine adjustment of the hanging posture of the balcony unit 10) is required at the stage where the balcony unit 10 is assembled to the housing 20 of the building main body 2, the above operation is performed inside the building main body 2.
